Textbook Question
Chapter 40, Problem 3S
In wild columbine flower morphology encourages cross-pollination However during the middle of the receptive period of the stigma, self-pollination can occurs if the flower was not previously pollinated If cross-pollination occurs after self-pollination then that pollen reaches the base of the style before the self-pollen. Discuss the adaptive significance of this reproduction strategy.

Mention two strategies evolved to prevent
self-pollination in flowers.
Sexual reproduction in plants is considered to be a source of variation creation. How reproduction mechanisms played their role in creating variation and also give view regarding the mechanism that could be responsible for causing a different type of pollination
In their experiments with the flowers of Begonia involucrate, Agren and Schemske (1991) observed that there was a
trade-off between what two characteristics?
Size of flower and number of flowers on inflorescence
Size of flower and pollination
Annual versus perennial reproduction
O Time and expense to grow the pollen tube versus cost of maintaining the flower on the tree

If pollen is transferred from the stamens of a flower to the stigma of the very same flower, is that cross-pollination or self-pollination? If it is transferredfrom the stamen of one flower to the stigma of another flower on the very same plant? If it is transferred from the stamen of one flower to the stigma of another flower on a different plant, but a plant that is a clone of the first one?

Parthenogenesisarrow_forwardIn regards to the life cycle of the flowering plants, one place meiosis takes place is; In the fully developed pollen grain In the growing seed In the calyx In the ovulearrow_forwardDuring double fertilization, one sperm will unite with the egg, forming a zygote. As mentioned in the lecture, a generative cell divides to form two sperm. How is the second sperm used during the process of double fertilization? 00 00 It fertilizes the flower by landing directly on the stigma, which is the sticky surface found above a flower's style and ovary. This depends on the type of plant. Land plants will allocate the sperm that is not united with the egg to the formation of different tissues through mitosis and cytokinesis. It forms a triploid cell by fusing with polar nuclei. This cell then divides and develops endosperm tissue. Since it was not the sperm to fuse with the polar nuclei, the sperm cell will degenerate.arrow_forward
